Revert "driver core: enforce device_lock for driver_match_device()"

This reverts commit 8d76b2488eb3cc0717ab81b60622cff4a5f90f79 which is
commit dc23806 upstream.

It causes boot regressions on some systems as all of the "fixes" for
drivers are not properly backported yet.  Once that is completed, only
then can this be applied, if really necessary given the potential for
explosions, perhaps we might want to wait a few -rc releases first...
